OSGILLATORY MOTOR.

Specification of Letters Patent. Patented Aug, 27, 1912.

Application filed January 18, 1910. Serial No. 538,758.

To all whom it may concern.

Be it known that I, RUDOLPH RAINALTER, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Oscillatory Motors, of which the following is a speciicat-ion.

My invention relates to improvements in oscillatory motors, and my object is to provide a simple automatic motor of this character for driving light machinery such for instance as washing machines.

The invention consists in the novel construction, combination, and arrangements of parts hereinafter described, and particularly pointed out in the claims, and in order that the invention may be fully understood reference will now be made to the accompanying drawings, in which:

Figure 1 represents a central horizontal` section of my improved motor. Fig. 2 is a vertical central. section on line II-II of Fig. 1. Fig. 3 is an inverted side elevation of an oscillatory piston employed in carrying out the invention. Fig. 4 is a broken; section of the motor cylinder with a partil tion therein in elevation. Fig. 5 is a vertical central section of the oscillatory piston. Figs. 6 and 7 are detail perspectives of tubul lar valves employed in carrying out the in Fig. 8 is a detail perspective ofi vention. one of the oscillatory levers for controlling the valves. section through the center of the cylinder and partition with the outlet valve removed. l

In carrying out the invention I employ a cylinder consisting of a jacket 1, an upper cylinder-head 2, and a lower cylinder-head 3, said cylinder-heads having circular grooves 4 and 5, respectively, to receive the beveled ends of jacket 1 in order to form a fluid-tight joint. The cylinder-heads are tightly drawn against the beveled ends of the jacket by a plurality of tie-bolts 6. The upper cylinder-head 2 has a centrally-disposed internally-threaded stuffing-box 7, to receive an inlet pipe 8 adapted to be connected by a hose to a faucet or other source of motive fluid. Cylinder-head 3 has a cen-- trally-disposed tubular extension 9, divided by a transverse partition 10 into a stuffingbox 11 and a lubricant chamber 12, which latter has an inlet 13 extending radially through the cylinder-head and normally closed by a plug 14. Cylinder-head 3 is also Fig. 9 is a broken horizontalI fits against the interior of the cylinder and prevents leakage of water between the same and the piston, said packing being held in position by a U-shaped clip 17a. Piston 16 is provided at its rear upper side with a tubular portion 18 extending through the stufling-box 7 and communicating with inlet pipe 8. Said tubular extension 18 leads to a chamber 19 in the piston, which latter is provided at. its lower rear portion with a shank 20, extending through lubricant chamber 12, and the stufling box 11, and adapted to be secured direct to the agitator of a washing-machine or other light machinery.

21 designates a strainer within the tubular extension 18 for straining the motive iiuid of foreign matter before it enters chamber 19 in the piston, which latter is provided at one side with a screw-plug 22, so that access may be had to the chamber for the placing or removal of a tubular valve 23, which controls the escape of the fluid from the chamber into the cylinder. Plug 22 is locked in position by two overlapping screws 22a. Valve 23 is divided by a partition 24 into a chamber 23ai and a chamber 23", which lead into the cylinder from chamber 19 with which they communicate through two peripheral rows of ports 25 and 25a, respectively, arranged at opposite sides of the partition, see Fig. 1. Valve 23 is also provided with a centrally-disposed peripheral flange 26 having beveled sides, one of which is adapted to engage a seat 27 in plug 22, and the other a seat 27a in the adjacent side of the piston. Flange 26 is narrower than chamber 19 so that valve 23 may move longitudinally and thus alternately bring the tlange 26 into engagement with it-s seats.

28 designates a partition, which in conjunction with the piston 16 divides the interior of the cylinder in two parts, and in order to prevent leakage of motive fluid from one part to the other, I interpose packing 29 between said partition and the tubular portion 18 of the piston. Partition 28 has a chamber communicating with-the a'retaining-nut 34. Heads' 31 and 32vhave.

Vbeveled sides 35 and 36 to engage beveled seats 37 and 38, respectively, in opposite sides of partition 28. Valve is provided near Vits ends with peripheral rows of inlet ports 39 and 40, and intermediateits ends with two outlet ports 41, which latter are in Constant communication with chamber 29a,` The len h of valve 30 exceeds the width of partition 2S so that it may move to and fro to alternately expose the ports 39 and 40, as will beliereinafter described.

42 and 43 designate levers bearing against the ends of bolt 33jand pivotally mounted upon vertical pins 44 and 45, respectively,

'" extending through lugs projecting from opposite sides ofpartition 28 and abutting at their 4ends against the cylinder-heads 2 and 3, which prevent said pins from moving up or down and thus becoming disconnected from the levers. Levers 42 and 43 are provided with pocket-s 46 and 47 for a purpose hereinafter referred to.

The operation, briefly described, is as follows: Nhen the several parts occupy the positions shown in Fig, 1, iuid entering chamber 19 throughy the tubular extension 18, lows from said chamber into the cylinder throughportsl 25 and chamber 23, and upon impinging against the piston, forces the same in the direction of arrow a. The

fluid also on entering pocket 46 of lever 42 causes said lever to firmly hold valve 30 against `seat 37 so that the fluid cannot escape to the exhaust tube 15 through perforations 39. As the tluid forces the piston in the direction of arrow a said piston in turn forces the fluid out of the cylinder through ports40 and 41 and the exhaustV 15. When valve 23 is broughty into contact with lever `4'?, it Vpushes the same backward and causes it to move valve 30 longitudinally to close ports 40 and open ports 39. The pressure of valve ,23 upon lever 43 moves said valve longitudinally to luncover `its ports 25 and close its ports25 so that the fluid instead of flowing through the same from chamber 19,

enters the cylinder through ports 25L and reverses the motion of the piston. i

Having thus described my invention, what I claim is:

1. A motor consist-ing of a cylinder, an oscillatory piston mounted therein, motive fluid supply means leading into the cylinder through said piston, a valve carried by the piston for controlling the entrance `of the iuid into the cylinder, a partition in the i" cylinder communicating Hwith anl exhaust port, a valve movably-mounted in the partition for controlling the How of motive fluid through said exhaust-port, and two levers engaging opposite ends of said valve to actuate the same, said levers being provided with pockets, for the purpose described.

2. A motor comprising an inlet valve, and

a movable cup-shaped closure for obstructing the port thereof. K

3. A motor comprising an inlet valve, and a cup shaped closure fulcrunied in registration therewith for obstructing the inlet valve port.

In testimony whereof I aix my signature, l`

in the presence of two witnesses. y
